Schiff base cobaltcomplexes, [CoIIIL2] · ClO4 (1) and [CoIIL2] · CH3OH (2) (L=4‐chloro‐2‐[(2‐ethylaminoethylimino)methyl]phenol), have been synthesized from the same Schiff base ligand and synthetic procedures, but with different cobalt salts. The complexes were characterized by elemental analysis, IR spectra and single crystal X‐ray diffraction. Each of the complexes consists of a [CoL2] complex moiety

compounds of cobalt(II) and zinc(II) with Schiff bases 4-chloro-2-[(2-ethylaminoethylimino)methyl]phenol and 4-chloro-2-[(2-piperazin-1-ylethylimino)methyl]phenol, respectively, were synthesized. The characterization of the newly formed compounds was done by elemental analysis, IR spectra, molar electric conductibility, and single crystal X-ray determination. The Co atom in the cobaltcomplex is in an
Two azido-coordinated Schiff base Cu(II) complexes with the formulae [Cu(L1)(N3)]·MeOH and [Cu(L2)(μ1,1-N3)] n , where L1 is the deprotonated form of 2-chloro-2-[(2-ethylaminoethylimino)methyl]phenol, and L2 is the deprotonated form of 2,4-dibromo-6-[(2-dimethylaminoethylimino)methyl]phenol, have been synthesized and characterized by physico-chemical and spectroscopic methods. The X-ray crystal structures of both complexes have been determined. The Cu atom in [Cu(L1)(N3)]·MeOH is four-coordinate in a square planar geometry, while [Cu(L2)(μ1,1-N3)] n is five-coordinate with a square pyramidal geometry. The molecules in [Cu(L1)(N3)]·MeOH are linked by intermolecular O–H···O and N–H···O hydrogen bonds, forming dimers. The molecules in [Cu(L2)(μ1,1-N3)] n are linked through end-on azido bridges, forming one-dimensional chains. The xanthine oxidase inhibitory activities of both complexes were evaluated.
